Title (EN) EXHAUST GAS TREATMENT DEVICE
(FR) DISPOSITIF DE TRAITEMENT DE GAZ D'ÉCHAPPEMENT
(JA) 排ガス処理装置
Abstract:
(EN) Nozzles provided inside of reaction columns require regular maintenance. When a crane or the like is used to remove a reaction column from an exhaust gas treatment device for the purpose of performing maintenance on such nozzles, costs increase and space for installing the crane is required. An exhaust gas treatment device is provided with an outer cylinder comprising an internal space that extends in the height direction from a bottom side where exhaust gas is introduced toward an upper side where exhaust gas is discharged. The exhaust gas treatment device is additionally provided with a branch section comprising branch pipes that are provided with a spray section for spraying a liquid for treating the exhaust gas in the internal space. The outer cylinder comprises openings through which the branch pipes can enter and exit.
(FR) Buses disposées à l'intérieur de colonnes de réaction nécessitant un entretien régulier. Lorsqu'une grue ou analogue est utilisée pour retirer une colonne de réaction d'un dispositif de traitement de gaz d'échappement dans le but d'effectuer un entretien sur de telles buses, une augmentation des coûts et de l'espace pour installer la grue sont nécessaires. Un dispositif de traitement de gaz d'échappement est pourvu d'un cylindre extérieur comprenant un espace interne qui s'étend dans la direction de hauteur à partir d'un côté inférieur où le gaz d'échappement est introduit vers un côté supérieur où le gaz d'échappement sort. Le dispositif de traitement de gaz d'échappement en est plus pourvu d'une section de bifurcation comprenant des tuyaux de bifurcation qui sont pourvus d'une section de pulvérisation pour pulvériser un liquide pour traiter le gaz d'échappement dans l'espace interne. Le cylindre extérieur comprend des ouvertures par lesquelles les tuyaux de bifurcation peuvent entrer et sortir.
(JA) 反応塔内部に設けられたノズルは、定期的にメンテナンスする必要がある。ノズルをメンテナンスすることを目的としてクレーン等を用いて反応塔を排ガス処理装置から取り外す場合には、クレーンを設けるスペースおよびコストが必要となる。排ガスが導入される底部側から排ガスが排出される上部側への高さ方向に延伸する内部空間を有する外筒を備える排ガス処理装置であって、排ガスを処理する液体を内部空間に噴射する噴射部が設けられる枝管を有する枝部を備え、外筒は、枝管が入出可能な開口を有する、排ガス処理装置を提供する。
